Performance Analysis of a Rate-Adaptive Dual-Branch Switched Diversity System
Abstract— In this paper, a performance analysis of a dualbranch switched diversity system operating on identically distributed Nakagami-m fading channels is presented. An adaptiv...

Why Do Block Length and Delay Behave Differently if Feedback Is Present?
Abstract--For output-symmetric discrete memoryless channels (DMCs) at even moderately high rates, fixed-block-length communication systems show no improvements in their error expon...

Generalized feedback detection for spatial multiplexing multi-antenna systems
Abstract-- We present a unified detection framework for spatial multiplexing multiple-input multiple-output (MIMO) systems by generalizing Heller's classical feedback decoding...

Multiuser broadcast erasure channel with feedback - capacity and algorithms
We consider the N-user broadcast erasure channel where feedback from the users is fed back to the transmitter in the form of ACK messages. We provide a generic outer bound to the ...

How to beat the sphere-packing bound with feedback
The sphere-packing bound Esp(R) bounds the reliability function for fixed-length block-codes. For symmetric channels, it remains a valid bound even when strictly causal noiseless ...
